To all whom it may concern:

Be it known that we, JOHN N. MQRTLMER' and EMILE L. S'rnanss, citizens of the Un it'ed States, and residents of Cleveland, 'couiityof Cuyahoga, and b'tate of Ohio, havejointly invented a new and useful improvement in Compression-Bibs, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention, while relating specifically to a compression bib, involves features of (:OliStl'llL'tlUll that are generally applicable to devices of the same character.

'lhe object of the invention is the provision of a bib or like device, wherein the valve will be thrown full open or full shut with a fractional turn of the stem (approximately a quarter turn) such as is required to operate a Fuller cock.

To the accomplishment of the foregoing and related objects, said invention consists of. the means hereinafter fully described, and particularly pointed out in claims.

The annexed drawing and the following description set forth in detail certain mech-' anism embodying the invention, such disclosed means constituting, however, but one of various mechanical IOIIIIS in which the principle of the invention may be used.

In said annexed drawing :l+'igure l is a Vertical sectional view of a bib, wherein our in'iprovement has been incorporated, and Fig. 2 is a plan view of the same.

'1 he specific device chosen for illustrative purposes is a sink bib of theQcompresSion type, as will be obvious from an inspection of the drawing just referred to, but it will be understood that it is immaterialso far as the inventive feature of the device is.con-. cerned, whether such device be in form a.

sink bib, a basin cock, bath cock or other iike fixture. Referring, then, to Fig. 1, such bib will he seen to comprise a casing A of usual forni provided with a transversely located valve seat a, to which in turn is fitted a valve rt borne by a valve stem A that is threaded in the upper portion of the casing.

. The intermediate threaded portion a of the stem is enlarged so as to form in effect a cylindrical barrel and the threadlthereonis made double and of such a pitch thata fraction a1 turn of the stem,"as has been indicated, will sutfice to throw the valve from its full open to its full shut position, and

"vice versa. All theadvantages of Fuller actly limit or stop the rotation of the stem A when the valve has been raised to its full open position. An exact quarter turn effect is thus'secured; indeed, in the manufacture of the device,,the stem is fitted in the casing, and then secured in place before its upper end is squared off to receive the actuating handle A The sides of the portion thus squared off will thus be seen to properly aline in both the open and closed positions in ques tion.

In Figs. 1 and 2, the handle is shown (in full lines) as lying transversely of the casing when the valve is closed,and as aliiied therewith (in dotted lines) when the valve is open. The operation of the device will hence bequite analogous to that of Fuller work, as has been already indicated without, howe\ er, embodying any of the detracting features. of the latter, which are tolerated'merely because of the desirability of having a valve that will open with a very small i'otative movement of the handle.

\ Qther modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, pro vided the means stated by any one of the following claims or the. equivalent of such stated means be employed.

o therefore particularly point out and distinctly Cltlilil as our invention 1.
